Beth, those studies have been done and that's what Survivor Buddy is all about. The investigators studied things like robot "body language" and sounds, for example, which is one reason the GUI was designed with help from Pixar engineers. The studies were done in the context of what worked and didn't work in the wake of 9/11. And personally, I think BEAR is scary, not cute.

Humans being rescued by Firefighters in full turn-out gear is pretty scary. A Firefighter wearing a SCBA with a full mask, sounding like Darth Vader is enough to send kids and adults crawling into greater danger rather than risk being 'saved' by the creature from your nightmares. Using rescue robots for size-up, search and rescue if possible will greatly reduce the need to put human responders into unknown risk scenarios. Wounded soldiers would know ahead-of-time that their rescue may be from a robot and would be more likely to accept that help.

One solution is sedatives. they can be implimented in the form of vapor or gas in the event of a panicing victim. in cases of fire a sleeping victim might breath less and incur less damage to lungs. they will strugle less and the load will be safer to carry. Im sure other features can later be added to drive even through walls of fire. Temporary water spray to cool the victim and protect them as the robot drives through extreme environment, etc...

The other solution is a more stable robot to carry a shifting load and a better trained victim. In the case of a solder being evacuated all of a sudden a wounded soldier might still be able enough to provide suppresive fire to defend himself/herself and the robot.

The big question is would a human in a panic situation not panic further if a robot (even a cute one like Bear) rolled towards them to try to carry them down the stairs or out of a building. Your first instinct might be to run away from the robot given the turmoil that's engulfing you, creating more of a flight instinct. I'm wondering how much they can test for those scenarios without replicating the actual desperation of the scene. And if that were indeed the case, then how effective could the robots actually be in saving lives.

When we wrote about the BEAR a few years ago, plans were for it to be able to lift a 250-lb man and "carry him down a flight of stairs," but it wasn't yet able to do that. Now, I see it's up to 500 lbs.
